I normally use the bash shell
on Unix and Linux systems. A shell is the user interface to the system.
The shell on Unix and Linux systems gives you the type of interface
you get with a command prompt on Windows systems. On older versions of
Windows you would be issuing DOS commands at the command prompt. As you
have batch files with DOS, with Unix and Linux shells you can create
scripts to automate your work, though you normally get a much richer
set of commands than with DOS.
Prior to the development of the bash shell there was a Bourne shell and
the name Bourne Again Shell (bash) comes from the name of that prior shell. The bash shell was created by Brian Fox in 1988. He continued to work on it until
1993. Chet Ramey joined Brian in the development of bash in 1989 and Chet
continued the work on bash after Brian ceased his development efforts on bash.
I've posted a few bash tips in Bash

Blosxom Calendar Plugin Bug
I use Blosxom for my blog and
the Blosxom Calendar Plugin to add a calendar to the blog. I
installed version 0.6i of the plugin on August 30, 2004. Today, I noticed that
if I click on the path link at the bottom of an entry where the path has
a directory as part of the path with a name beginning with a number, clicking
on that link generates the internal server error shown below.
The server encountered an internal error and was
unable to complete your request.
Premature end of script headers: blosxom
If you think this is a server error, please contact
When I looked in the site's error log, I found the following.
[Mon Jul 25 19:18:21 2005] [error] [client 188.8.131.52] Cannot handle date (0, 0, 0, 1, 11, 2800) at /support/blog/plugins/calendar line 214, referer: http://support.moonpoint.com/blog/blosxom/index.html?find=Dell&plugin=find&path=
When I checked line 214 in the calendar plugin I saw the following.
$monthstart = timelocal(0,0,0,1,$month-1,$year-1900);
The problem appears to be triggered whenever there is a directory with
the directory name starting with a number in part of the path. I had a
directory with /pc/hardware/dell/4700 as part of the path. I renamed the
4700 directory to d4700 and the problem went away. I changed it to 4700d
and the problem reoccurred. I changed it to 3800 and the problem remained.
Since I didn't have time to carefully examine the code in the calendar
plugin, I finally just changed the directory to dimension_4700 and left
it at that.
I thought there might be a later version of the plug-in at the
developer's website, but the 0.6i version is the one still posted there.

I installed ht://Dig because I
thought I had placed certain information on my website, which I waned
to refer to again, but couldn't locate it. I have a search tool for
the blog, but that will only search the blog's content. Since I couldn't
find the information with that tool, I thought I might have placed the
information in a file or files that weren't part of the blog's entries.
So I installed htdig and used it to search the entire site. I still couldn't
find the information, though I can recall creating a webpage with the
Oh well, I'll just have to keep looking or figure out how to do what I need
to do again. One of the reasons I created the blog was to serve as a reference
when my memory fails me on how I resolved a problem in the past. But, if
I didn't post the information here, it's going to take me much longer to
locate it or figure out again the steps I took previously.
So I won't have that problem with installing htdig again, I've posted my
notes in the blog.
Hopefully, it might help someone else as well in resolving problems
or answering questions about setting it up so it can be used with multiple
websites on the same server.

Importing An Outlook Express Address Book into Outlook Express
If you need to import an Outlook Express address book
into Outlook Express on another system or into the address book of another
account on the same system, take the steps listed below.
Locating an Address Book
Locate the previous Outlook Express address book. It will be a .wab file
(presumably this stands for "Windows Address Book"). You won't be able
to locate it if the Windows Explorer is using the default folder settings,
which don't allow you to view hidden and system files. You need to change those
settings first, if you haven't previously done so, to display hidden and system
files (instructions for viewing
hidden and system files).
The address book, which will have a "wab" extension, will likely be under
C:\Documents and Settings\username\Application Data\Microsoft\Address Book,
where "username" is the relevant user's userid, e.g. "JSmith".
If you are importing the address book into an account on the same system, you
can proceed to the step of importing it into Outlook Express. Otherwise copy it
to the other system. There may also be a file with an extension "wab~". That
is a backup file, which you can ignore. If you want to view the entries in the
address book, you can double-click on the file and look under "Main Identity's
Contacts" for the list of addresses in the address book
Importing the Address Book
- Click on "Addresses" to open the address book.
- Click on "File" and select "Import" followed by "Address Book (WAB)".
- Browse to where the address book is stored, click on it to select it and
then click on the "Open" button, which will import the addresses from that
file. You should see "The import process completed successfully" when
the operation is complete.

Starting and Stopping No-IP Service
If your system is connected to the Internet by a dynamic Internet Protocol
(IP) address, but you need to be able to reach the system with a fixed
name, you can use a dynamic Domain Name System (DNS) service, such as the
one provided by No-Ip.com. You can
install their dynamic update client on the system and it will report its
IP address to No-Ip's DNS servers.
If the No-IP Dynamic Update Client (DUC) software on a system is not
updating the IP address for the system with
No-IP's servers, you can start and stop the service from the command line
(you may need to be logged into an account in the administrator group) by
using the following commands:
net stop noipducservice
net start noipducservice
You can determine when a system last updated its address with No-Ip's
servers by logging into your No-Ip account and under "Hosts/Redirects",
click on "Manage". Locate the name of the system in question and click on
"Modify" for it. You will see a "Last Update" for it.

I run various sendmail log file processing scripts nightly to process
the day's maillog file. At midnight, the maillog file in /var/log is
rotated to /var/log/maillog.1. The log file processing scripts then
analyze maillog.1 and produce reports based on its contents to allow
me to track what is happening on the mail server. I added a Perl
script, smlogstats, to the daily email log processing scripts.
The original smlogstats script is available from
http://www.salug.org/~wcb/smlogstats.pl.txt. That script
used a hardcoded output file. Since I want to maintain an
archive of sendmail reports, I modified the script slightly
to optionally allow the output file to be specified. The modified
script has the following usage:
usage: smlogstats.pl [ -d ] [ -l logfile ] [ -o htmlfile] [ -t n ]
-d print detail
-l full path name to logfile (default /var/log/maillog)
-o full path to the html output file (default stats.html)
-t print top n addresses (default 10)
I use another script,
to produce a log file when it is run by cron every night at midnight.
The script puts its output in
/home/logfiles1/www/support/internal/logs/mail/smlogstats/$(date --date=yesterday +%Y)/$(date --date=yesterday +%m%d%y).html.
The directory path includes a directory with the year specified, i.e.
date --date=yesterday +%Y, followed by the file name, which is
yesterdays date in mmddyy format followed by an extension of html.
Script - smlogstats.pl
